Longden Company recently completed a 5,000 square foot server lab infrastructure upgrade project for Casa Systems in Andover, MA. This project included demolition of existing wet sprinkler and mechanical systems to allow for installation of a pre-action sprinkler system tied into a special hazard fire detection system, along with the implementation of Liebert CRV precision in-row cooling units and Liebert PDX perimeter cooling units to supply cool air to server racks and modem racks, respectively. Longden also installed new electrical switchgear and power distribution, including Starline track busway, for point-of-use plug-in capabilities.read more

Longden designed and built this dedicated server room for a financial institution located in Burlington, MA. We managed all aspects of construction, including carpentry, electrical, HVAC and mechanical systems. Equipment installed includes redundant 20KW in-row Liebert CRV air-cooled AC systems, redundant 30KW Emerson EXM UPS systems with A/B whip distribution to critical load, a preaction sprinkler system with dedicated smoke detection and panel. All systems are protected by a 250KW natural gas Caterpillar generator. This also backs up the call center and disaster recovery functions for this corporate office.read more

This server room project includes a 20 kVA Liebert UPS system, overhead cable tray and redundant power distribution to each rack. HVAC design incorporates two Liebert CRV in-row cooling units for redundant cooling. A dedicated detection and fire alarm panel with preaction sprinkler system protects the server room. And, the entire facility is backed up by generator power.read more

Containment and proper routing of airflow in a server room is critical to uptime performance and energy efficiency. Aisle containment doors and roofs are an excellent way to trap cold air within the cold aisles and ensuring there is no bleedover of air to the hot aisles. However, if the configuration of the server room is not conducive to physical containment, or there are budget constraints, Virtual Containment may be the answer. Instead of relying on traditional perforated floor panels, Virtual Containment utilizes directional flow perforated or louvered panels to direct air to the front surface of the rack.read more
